Latest Patents

Kenzo Nakazawa's latest patents include a thermographic material and recording method. This invention comprises a support and a recording layer that contains a photolytic free radical generating agent. This agent is capable of providing a free radical upon light absorption, along with a dye that is decolored by the free radical and an anti-decolorizing agent. The unique aspect of this invention is that the photolytic free radical generating agent and dye are contained in a microcapsule, while the anti-decolorizing agent is present outside the microcapsule. An image is formed by heating the thermographic material to mix the anti-decolorizing agent with the photolytic free radical generating agent and dye, creating a latent image. The heated material is then exposed to light, allowing the dye at the latent image portions to remain colored while the dye at other portions is decolored.

Another significant patent is a light- and heat-sensitive recording material and recording method. This invention features a support with a light- and heat-sensitive layer that contains a photo-color-forming element. This element comprises a photodecomposable compound and a color-forming element that reacts with the decomposition product of the photodecomposable compound. The photo-color-forming element is imagewise heated to create a latent image, which is then exposed to light to form a color.
